Abstract: 339,768. Field, (nÚe Simmons), G. A., Field, J. H., and Field, A. B., (Representatives of Field, M. B.). Nov. 22, 1929. Magnetic compasses.-In a liquid compass the moving system does not carry a card but is provided with four direction indicators co-operating with an adjustable ring, the indicators being formed of thin metal strips functioning as damping vanes moving edgewise on in the liquid and the system being so proportioned that its movements are aperiodic. The compass is direct reading on a notation system either of 90‹-0-90‹ or of 0‹-360‹. In Figs. 1 and 2 the moving system, comprising the magnets 2 and the direction indicators 3 formed of metal strip movable edge-on in the liquid, is pivoted at 1<a> within the bowl 1 which is closed by a glass 4 and bezel 5. Rotatably mounted above the bezel is a ring 8 carrying a glass pane 7 and provided with a scale 8 and with wires 9 parallel to and equidistant from the N-S line on the scale. Fixed within the bowl at the level of the indicators 3 is a semi-annular scale 11 graduated 90‹-0-90‹ with its zero coinciding with the lubber point. In operation the ring 6 is turned until the marking on the scale 8 representing the desired course coincides with the lubber point and the vessel is steered to bring the N point of the moving system against the N point of the scale. If the course is to be departed from temporarily, the new course may be read off on the scale 11 without disturbing the ring 6. To steady the bowl, each gimbal pivot 12 is provided with a sheave 13, Fig. 5, around which passes a cord 14 tensioned by a spring 15. Fig. 8 shows a form for dashboard mounting on an aeroplane &c., the bowl 1 being mounted in a case 27 having lugs 29 for attachment to the dashboard 26. The scale 8 and filaments 9 are photographed on the under side of the glass 7 and an additional pair of filaments extending E-W are also photographed on the glass. The bowl is surmounted by an optical arrangement comprising mirrors 34, 35 so that an observer looking through the window 36 sees an unreversed image of the moving system and scale. The mirror 35 can be adjusted about a pivot 40 by a spindle 37 and worm gear 38, 39. Each direction indicator 3 consists of a thin metallic stamping and is fitted with a tube 45, Fig. 2, containing radium compound.

Abstract: 1,096,868. Simulation device. NAUCHNOISSLEDOVATELSKY INSTITUT MEKHANIKI I FIZIKI PRI SARATOVSKOM UNIVERSITETE. Aug. 24, 1965, No. 36247/65. Heading G4G. In induced current method simulation apparatus simulating fields described by the Laplace equation and adapted for visual observation and photography of the spectra of space harmonics and the field distribution of linear periodic systems, a model of a linear periodic system to be investigated comprises radially disposed electrodes mounted on a dielectric table over which an electrostatically charged probe is rotatable by a motor at variable and measurable distances and induces potentials in the several electrodes (Fig. 2, not shown). Boundary conditions are set by a circuit wherein plural identical adding circuits 1 (Fig. 1) each comprise a fixed and a variable resistor 4, 5 in series between earth and a common line alternatively connectable by switch 18 to a potentiometer 17 and a summation amplifier 20 exciting an oscillograph and a low frequency spectrum analyser (Fig. 3, not shown). The electrodes 2 are respectively connected over contacts 7, 9 to the functions of respective adding resistors and to jacks 15, and a current meter 12 switchably interchangeable with socket 25 connectable to an extension meter is connected in series with a ballast resistor equal in value to the summation resistors 4 and plug 14 engageable with successive jacks. It is shown mathematically that the meter may be graduated in percentages. In operation, with switch 18 in position A, resistors 5 are set in correspondence with the required potentials to be applied to electrodes 2 of the model of the linear periodic system under investigation, by inserting plug 14 in successive jacks 15. Initially with a resistor 4 short-circuited, potentiometer 17 is set to produce full-scale deflection of meter 12 and referred to this reading as a percentage appropriate, values of potential are set in the respective jacks by adjusting corresponding resistors 5, whereby predetermined boundary conditions are established. The model is mounted (Fig. 2, not shown) so that corresponding contacts 7 are connected to electrodes 2 in connection with contacts 9 of the adding circuits, and plug 14 is removed. With switch 18 in position B, the probe is rotated over the electrode series of the model and induces signals therein which are summed with the respective set-in potentials, which represent weighting coefficients. The resultant sum signal whose time variation is proportional to the space distribution of the field component being investigated is amplified and displayed on the oscillograph and spectrum analyser. The displacement of the probe from the model is variable to enable the field to be investigated at different distances from its surface.

Title: Improvements in and relating to trolleys for electric vehicles
IPC: B60L5/14
Filed: 1934-12-19
Abstract: 449,086. Trolly collectors of electric vehicles. BAMKIN, B. S., 108, Portland Road, Hucknall, Nottinghamshire, and PEARSON, L. H., 54, Long Row, Nottingham. Dec. 19, 1934, Nos. 36397/34 and 32800/35. [Class 104 (iii)] A trolly collector comprises a two-part pole, of which the lower part 3 pivots on a horizontal pivot 2 on a bracket 1 rotatable on a vertical axis. The upper part 7 is pivoted at 6 inside socket 5 on the part 3, and is locked to the latter by a spring catch 8. If the collector leaves the wire, the upward swing of the pole produces relative sliding movement of a rod 19, which pushes the latch 8 upward out of engagement with the socket 5, so that the part 7 of the pole can fall by gravity. The fall is limited by a cable 22, passing under the part 7 and over pulley 23, and anchored to a collar 25 slidable on the part 3 against the action of a spring 26. The pull of the cable prevents excessive lateral swing of the pole and returns it to parallelism with the centre line of the vehicle. In another form, the catch is released by the upward movement of the trolly wheel acting through levers and a cable on a spring rod connected to the catch. Means may be provided to reduce the tilt of the part 3 of the pole in case of dewirement.

Title: Apparatus for the production of artificial yarns with fluctuations in denier
IPC: H03K3/84
Filed: 1956-11-28
Abstract: <PICT:0829361/IV (a)/1> An apparatus for the production of artificial yarns with random fluctuations in denier is provided with a control impulse generator adapted to receive impulses from a magnetic tape or magnetic disc bearing irregularly distributed impulse markings and to utilize these impulses for the production of artificial slub yarns, and comprises an electromagnetic reproducing device, an electric amplifier and a means for producing artificial slub yarns controlled by the operation of one or more electric relays, the reproducing device, amplifier and the relay or relays being so interconnected in an electric circuit that, on the passage of the impulse markings on the tape or disc past the reproducing device, corresponding electric impulses actuate the relay or relays and so cause fluctuations in the denier of the artificial yarn being produced, which fluctuations correspond to the irregularly distributed impulse markings on the magnetic tape or disc.  The impulse markings may be applied to the magnetic tapes or discs by recording cosmic rays over a long period of time on a master magnetic tape or disc, checking the irregularity of the incidence of rays during this time with regard to their suitability for controlling denier fluctuation impulses, and extracting from this master tape or disc that section which only contains irregularities suitable for use From this section of a master tape or disc, magnetic tapes or discs which no longer contain any incidence periods of unsuitable rays are then produced by magnetic transfer.  As shown, an endless magnetic tape 1 having irregularly distributed impulse markings is scanned by a soft iron core 2 situated inside a coil 3, the induction of which caused by variation in the magnetic field intensity influences the grid of an amplifier valve 4, which in turn attracts a switch relay 6, as each controlling impulse is received, by way of a transformer 5. After the impulse is complete, the switching relay falls off again.  Depending on the position of the relay, one or other of two different current couplings 7, 8 of the spinning machine (not shown), is actuated, so that, for example, a supplementary spinning pump is temporarily switched on or the rate of withdrawal of the yarn is reduced or increased.
